Mental disorders, also known as mental illnesses, are conditions that significantly affect an individual’s emotions, thinking, behavior, and ability to function in daily life. These conditions can disrupt work, school, and social interactions, often requiring professional evaluation and treatment to improve quality of life.
Early identification and effective intervention are critical for managing mental disorders and preventing future complications. Diagnosis is typically conducted by healthcare professionals using standardized tools like the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders) or the ICD-11 (International Classification of Diseases).
